LEV3 High Alumina 벽돌 소개

Lev3 high alumina brick is one of the common 불응 성 물질, which are formed and calcined from bauxite or other raw materials with high alumina content.

Characteristics of grade 3 높은 알루미나 벽돌

1. 화학 성분: AI203 content should be between 50% 그리고 70%, Si02 content should be below 30%
2. 부피 밀도: should be above 2.20 g/cm’.
3. Apparent porosity: should be below 22%.
4. Normal temperature compressive strength: should be above 40MPa.
5. Load softening temperature: should be above 1350’C.
6. 열충격 저항: should be above 10 타임스.
7. 열팽창계수: should be below 5.0×10-6/기음.

Application of Lev3 high alumina brick

• Used for lining blast furnaces, 뜨거운 폭발로, electric furnace roofs, blast furnaces, 반사로, and rotary furnaces.
• Refractory heat expansion rate is small, not easy to deform, neatly formed
• Carefully selected materials insist on quality first, preferred materials are durable
• The clay is very pure and fine, has high density, is not easy to wear on the surface, has high-temperature resistance, 높은 압축 강도, high load softening temperature, high-temperature volume, stability, and deformation performance are excellent
